Change SSH Port in Linux Easily

You can easily change SSH port in Linux systems. You can use ports ranging from 0 to 65535. The port number 0 is reserved and cannot be used. The default SSH service listen on port 22. Just this port with some other ports.

To change and update SSH port, edit OpenSSH configuration file

$ sudo vi /etc/ssh/sshd_config

In the configuration file, search for port 22 . When you find port 22, uncomment the port and replace it with some other nonstandard port (let’s take 2220.) Now save the config file.

Search for
Port 22

Replace with
Port 2220

Now, restart the SSH daemon to apply changes.

$ sudo systemctl restart ssh 

Awesome, your ssh server login port has been changed successfully.

$ ssh -p 2220 [email protected]
